WRITING CONVENTIONS FOLLOWED IN THIS MANUAL

The writing conventions described below have been followed to simplify instructions and avoid

unnecessary repetition.

PREPARATION

MOBILE INSTALLATION

When installing the transceiver, select a safe, convenient location inside your vehicle, which will

minimize dangers to your passengers and yourself while the vehicle is in motion. Consider

installing the unit at an appropriate position so that your knees or legs will not strike it during

sudden braking. Try to pick a well ventilated location which shielded from direct sunlight.

1 Install the mounting bracket in the vehicle, using the supplied self-tapping screws (4), flat

washers (4), and spring washers (4).

• The bracket must be installed so that the 3 screw hole positions on the side of the mounting

bracket are towards the rear of the bracket.

2 Place the transceiver, then insert and tighten the supplied hexagon SEMS screws (4) and flat

washers (4).

• Carefully check that all hardware is tightened to prevent the bracket or transceiver from

loosening for vehicle vibration.

[SEMS screws]

• Determine the appropriate angle of the transceiver, using the 3 screw hole positions on the side

of the mounting bracket.

DC POWER CABLE CONNECTION

Caution: locate the power input connector as close to the transceiver as possible.

MOBILE OPERATION

The vehicle battery must have a nominal voltage of 12 V. Never connect the transceiver to a 24 V

battery. Be sure to use a 12 V vehicle battery that has sufficient current capacity. If the current to

the transceiver is insufficient, the display may darken during transmission, or transmit output

power may drop excessively.

1 Route the DC power cable supplied with the transceiver directly to the vehicle’s battery

terminals, adopting the shortest path from the transceiver.

• If using a noise filter, it should be installed with an insulator to prevent it from touching metal

on the vehicle.

•We recommend you not use the cigarette lighter socket as some cigarette lighter sockets

introduce an unacceptable voltage drop.

• The entire length of the cable must be dressed so it is isolated from heat, moisture, and the

engine secondary (high voltage) ignition system/ cables.

2 After the cable is in place, wrap heat-resistant tape around the fuse holder to protect it from

moisture and tie down the full run of cable.

3 To prevent the risk of short circuits, disconnect other wiring from the negative (–) battery

terminal before connecting the transceiver.

4 Confirm the correct polarity of the connections, then attach the power cable to the battery

terminals; red connects to the positive (+) terminal and black connects to the negative (–) terminal.

• Use the full length of the cable without cutting off excess even if the cable is longer than needed.

In particular, never remove the fuse holders from the cable.

5 Reconnect any wiring removed from the negative terminal.

6 Connect the DC power cable to the transceiver’s power supply connector.

• Press the connectors firmly together until the locking tab clicks.

【fuse holder】

FIXED STATION OPERATION

In order to use this transceiver for fixed station operation, you need a separate 13.8V DC power

supply [not included]. The recommended current capacity of your power supply is 12A.

1 Connect the DC power cable to the regular DC power supply and ensure that the polarities are

correct (Red: positive, Black: negative).

• Do not directly connect the transceiver to an AC outlet.

• Use the supplied DC power cable to connect the transceiver to a regular power supply.

• Do not substitute a cable with smaller gauge wires.

2 Connect the transceiver’s DC power connector to the connector on the DC power cable.

• Press the connectors firmly together until the locking tab clicks.

[ fuse holder]

Notes:

For full capabilities performance of your transceiver, we recommend using the optional PS-33

(20.5A, 25% duty cycle) power supply.

Before connecting the DC power supply to the transceiver, be sure to switch the transceiver and

the DC power supply OFF.

Do not plug the DC power supply into an AC outlet until you make all connections.

REPLACING FUSES

If the fuse blows, determine the cause, then correct the problem. After the problem is resolved,

replace the fuse. If newly installed fuses constantly blow, disconnect the power cable and contact

your authorized HYS+LOGO dealer or an authorized HYS+LOGO service center for assistance.

Caution: Only use fuses of the specified type and rating; otherwise the transceiver could be

damaged.

Notes: If the transceiver has been used for a long period when the vehicle battery is not fully

charged, or when the engine is OFF, the battery may become discharged, and will not have

sufficient reserves to start the vehicle. Avoid using the transceiver under these conditions.

ANTENNA CONNECTION

Before operating, install an efficient, well-tuned antenna. The success of your installation will

depend largely on the type of antenna and its correct installation. The transceiver can have

excellent performance if the antenna system and its installation are given careful attention.

Use a 50 Ω impedance antenna and low-loss coaxial feed line that has a characteristic impedance

of 50 Ω, to match with the transceiver input impedance. Coupling the antenna to the transceiver

via feed lines having an impedance other than 50 Ω will reduce the efficiency of the antenna

system and can cause interference to nearby broadcast television receivers, radio receivers, and

other electronic equipment.

Note: E market models use an N-type antenna connector while other models use an M-type

(SO-239) connector.

Caution: Transmitting without having connected an antenna or other matched load may damage

the transceiver. Always connect the antenna to the transceiver before transmitting.

All fixed stations should be equipped with a lightning arrester to reduce the risk of fire, electric

shock, and transceiver damage.

[antenna connector, to antenna, feed line connector]

ACCESSORY CONNECTIONS

EXTERNAL SPEAKER

If you plan to use an external speaker, choose a speaker with an impedance of 8 Ω. The external

speaker jack accepts a 3.5 mm mono (2-conductor) plug. We recommend using the SP-50B

speaker.

MICROPHONE

For voice communications, connect a 600 Ω Microphone equipped with an 8-pin modular plug

into the modular socket on the front of the main unit. Press firmly on the plug until the locking tab

clicks.

Attach the supplied Microphone hanger in an appropriate location using the screws included in the

screw set.

PC CONNECTION

To utilize the optional MCP-1A software, you must first connect the transceiver to your PC using

an optional programming cable (via the Microphone jack).

The MCP-1A is free downloadable software available from HYS+LOGO at the following URL:

http://www.trustcomnctn.com or ask our sales to send it by e-mail.

Note: Ask your dealer about purchasing a programming cable.

CONNECTING TO A TNC [E market models only ]

To connect an external TNC to the transceiver, use an optional PG-5A cable. The DATA connector

on the rear of the transceiver matches with the 6-pin mini-DIN plug on this cable.

Note:

If the external TNC has a common pin for 1200 bps and 9600 bps data output, connect this pin to

the DATA connector PR9 pin. Shorting the PR9 and PR1 pins will cause the TNC to malfunction.

Adjust the transceiver data communication speed (1200 bps or 9600 bps) as necessary {page 54}.

If DC voltage is input to the PR1 pin, the external TNC may not function. If this problem

happens, add a 10 µF capacitor between the PR1 pin and the TNC. Be careful with the polarity of

the capacitor.
